Projects

My software products and selected client work.

A mix of my own products and selected client sites. Most of my client work is around SQL Server, but I also build software products and take on occasional web projects.

Things I am building

Product work where I shape the logic, data model, decision flow, and long-term system direction directly.

Chrome extension popup

Hungarian news Chrome extension

Mai hírek rss

A Chrome extension that puts headlines from ten Hungarian publishers into one searchable popup or side panel.

I built it for a quick scan of the day without opening ten news sites. Hírkép groups similar headlines from different publishers so the change in emphasis is easy to spot. Search, unread filters, saves, story follows, keyboard shortcuts, and optional notifications keep the feed manageable.

Offline password manager

Passary

A local-first password manager built around data ownership, isolation, and zero-knowledge operation.

Zero-knowledge password manager

No accounts / no tracking

Argon2id + AES-256-GCM

Built for privacy

zero-knowledgelocal-firstsecurityprivacyweb app

Project page

The starting point here was simple: passwords should not live in a cloud vault by default. They should stay with the user, locally, encrypted. The security model is built around Argon2id + AES-256-GCM, with a zero-knowledge approach and as small an attack surface as possible. Right now the focus is continued product work: browser extension, mobile direction, and later self-hosted or sharing use cases.

macOS menu bar utility

ResoSwitch

A native macOS menu bar app for switching display resolutions, HiDPI modes, and external monitor layouts without opening System Settings.

Project page

The problem is small but annoying: macOS can change display modes, but the control is buried when you need it often. ResoSwitch puts the useful choices in the top-right menu bar, with per-display favorites, Cmd+number shortcuts, and a safety prompt for unusual modes. The current public release ships as a PKG or DMG for macOS 13 and newer. It is still unsigned and not notarized, so installation is not yet as smooth as a polished Mac app should be.
